Dusty missive

 is an item in Tyranny.

Description
This missive is a reply intended for Sage Renata. It urges her to make an important decision about the future of their guild. Evidently the Sages were often used as mediators between the armies, often times because Graven Ashe simply refused to work with the Voices of Nerat due to the troubled past between the two.
